Featured in PASCO’s Elementary School Science Teacher Guide
Features 29 inquiry based labs designed for elementary students and coordinated with the standards for life, earth and physical sciences.
Investigating Sound Levels
Students recognize that continuous sound is made by vibrating objects, and can be described by its pitch and volume. Students explore different continuous sounds by studying the changing volume.
To understand this content, students:
- Describe sound volume using drawings and verbal descriptions.
- Hum in a variety of ways near the sound sensor and test the effect of a "megaphone".
- Compare graphs of sound levels and draw conclusions about sound and vibration.
Sensors / Equipment Used:
Allows students to conduct all three measurements simultaneously and continuously. For use with PASPORT Interfaces.
Allows an additional two meter length extension on all PASPORT sensors.
